When two-speed motor functionality is used, these settings allow the selection of proper parameters for the thermal
model when the motor is switched to the second speed. There is one thermal model in the M60, and it has inputs for
overload conditions from calculations at both speeds. As such, the accumulated thermal capacity is calculated from
overload contributions at each speed.
See the Thermal Model section earlier for details on settings for the thermal model at the second motor speed.
